摘要:
Provided is a liquid crystal composition that satisfies at least one of characteristics such as high maximum temperature of a nematic phase, low minimum temperature of a nematic phase, small viscosity, large optical anisotropy, large dielectric anisotropy, large specific resistance, high stability to ultraviolet light and high stability to heat, or that is suitably balanced between at least two of the characteristics; and provided is an AM device. The liquid crystal composition having a nematic phase includes a three-ring compound having a specific difluoromethyleneoxy bond having large dielectric anisotropy as a first component, a specific three-ring compound having large dielectric anisotropy as a second component, a specific four-ring compound having high maximum temperature as a third component, and a specific two-ring compound having high maximum temperature and small viscosity as a fourth component, and the liquid crystal display device contains this composition.
